ABSTRACT:
This paper presents the design, implementation, and performance evaluation of a low-cost, portable vibration detection system for safety monitoring applications. The proposed system utilizes an ADXL335 triple-axis accelerometer as the primary sensing element, an Arduino UNO microcontroller for data acquisition and processing, a 16×2 I2C LCD for real-time display of vibration intensity, and a piezoelectric buzzer for audible alert generation. The system continuously monitors vibration levels along three orthogonal axes (X, Y, Z) and triggers an alarm when predefined threshold values are exceeded, indicating potentially hazardous vibration events. The complete hardware prototype was developed with a total component cost of approximately ₹900 (INR), making it highly accessible for educational institutions, small laboratories, and residential safety applications. Experimental results demonstrate reliable vibration detection across a frequency range of 0.5–500 Hz with a sensitivity of approximately 300 mV/g. The system successfully distinguishes between normal ambient vibrations (below threshold) and potentially dangerous vibration events (above threshold), with an average response time of less than 100 milliseconds. This work contributes to the development of affordable early warning systems for seismic monitoring, structural health assessment, and industrial vibration surveillance.
